Ancalomicrobium adetum

A adetum image


About this microbe: James T. Staley


A. adetum produces several long prosthecae from its cells which divide by budding. It is a member of the Alphaproteobacteria. It is immotile, but produces gas vesicles under certain conditions. A. adetum is the only prosthecate bacterium known to grow anaerobically. Remarkably it carries out a mixed acid fermentation and the products of that fermentation are exactly the same as Escherichia coli a member of the Gammaproteobacteria.
